Stall warning logic

[Cf10]

I was on an approach while we were configuring to land but our amber band and clacker were not decreasing as we took flaps. We elected to go hold and troubleshoot. We used our wing anti-ice during flight but it was off at the commencement of the approach. I know that using the wing anti-ice during flight will reset the stall warning logic for the remainder of flight but in holding we turned the wing anti ice on and then off to see if the valve was stuck even though the light indicated it was closed. Any ideas why the amber band or clacker didn’t decrease? Thank you!
